Tyler’s Exploding Axes

You conjure 3 throwing axes of fire and fling it at a creature within range. Make a ranged spell attack against a target for each axe. On a hit, the target takes 1d8 fire damage and they axe sticks to the creature. On a miss the axe sticks to the creature’s space but not the creature itself. As a bonus action, you can detonate any existing axes within 60 feet. Each axe causes each creature within 5 feet of it to succeed on a Dexterity saving throw or take 2d4 fire damage or half as much on a success. 

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, you create one additional axe for each slot level above 3rd.
